Patents by Inventor R. Paul Boisseau

R. Paul Boisseau has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20160250500
    Abstract: A multi-resolution detector includes a high-resolution pixelated electrode and a low-resolution pixelated electrode. The high-resolution pixelated electrode includes a plurality of sub-arrays of first pixels. Each respective first pixel at each relative position in each sub-array is electrically connected in parallel with one another. The low-resolution pixelated electrode includes a plurality of second pixels. A control system receives as inputs an output from each pixelated detector. The control system uses the inputs to determine a physical position and a transverse intensity distribution of an incident charged particle pencil beam at the resolution of the high-resolution pixelated electrode.
    Type: Application

  • Patent number: 9333376
    Abstract: A system for calibrating a charged particle pencil beam includes a first pixelated detector, a second pixelated detector, a beam stop, and a diagnostics system. The first and second pixelated detectors measure the pencil beam at positions proximal and/or distal to an isocenter plane. The beam stop is configured to detect an energy level of the pencil beam. The diagnostics system is configured to transmit a signal to request a generation of the charged particle pencil beam at different settings. The diagnostics system is also configured to update a calibration parameter for each setting based on the data received from the pixelated detectors and the beam stop.

  • Patent number: 9293310
    Abstract: An ionization chamber with spatial distribution electrode for monitor hadron beam currents used for therapeutic treatment. Ionization chamber comprises humidity control, environmental sensing and real-time correction thereof. A flexible hermetic seal provide for ambient pressure equalization. X-Y electrode planes measure Gaussian distribution of incident particle beam. Methods described herein are suitable to fabricate highly accurate, low scattering electrodes with high spatial resolutions.
